2027 Medicare Appeals: New AIC Thresholds Explained

Every billing office has a stack of denials that sit in a gray zone: too large to write off without a second look, too small to justify weeks of staff time. In 2027 the dollar boundaries of that gray zone move slightly. They move in one place only, and it is easy to get wrong.

What Changes on January 1, 2027

CMS published its annual adjustment on September 16, 2026. For requests filed on or after January 1, 2027, the amount-in-controversy (AIC) threshold is $200 for an Administrative Law Judge hearing and $2,000 for judicial review in federal district court. The ALJ figure is not new. It was $200 in 2026 and stays at $200. The judicial review threshold rises from $1,960 to $2,000. Both figures follow a statutory formula tied to the medical care component of the consumer price index, rounded to the nearest $10. The practical consequence is narrow but real. A dispute with $1,980 remaining in controversy cleared the bar in 2026 and would not clear it in 2027. The judicial review threshold applies at the time the request is made, so the year a case reaches that stage matters.

How the Amount Is Counted

The threshold is not the billed amount. Medicare contractor guidance describes the calculation as the amount charged, minus Medicare payments already made or awarded, minus any applicable deductible or coinsurance. A $500 disputed charge with $100 in applicable coinsurance, for example, leaves $400 in controversy if no Medicare payment has already been made or awarded and no other deductible or coinsurance amount applies. Teams that compare the full charge against the threshold overstate what they can appeal.

Claims involving similar or related services can sometimes be combined to reach the ALJ threshold, but only under the conditions set out in 42 CFR § 405.1006. Among other requirements, the claims must have reached the required appeal stage, the request to aggregate them must meet applicable filing rules, and the claims must involve similar or related services or, in cases involving multiple appellants, common issues of law and fact. This is not permission to combine any small denials at will. The regulation should be checked before a billing team builds a workflow around aggregation. This is where some small denials may become appealable while others remain below the threshold.

Where the Thresholds Sit in the Process

The first two levels, redetermination by the Medicare contractor and reconsideration by the Qualified Independent Contractor, carry no minimum dollar amount. The ALJ level is the first with a financial gate. After that:

An ALJ hearing request is due within 60 days of receiving the reconsideration notice.
Review by the Medicare Appeals Council has no amount-in-controversy requirement.
Judicial review requires the threshold to be met and a filing within 60 days of receiving the Council’s decision.

The same threshold amounts apply to Part C and Part D appeals under the CMS notice, although who holds appeal rights differs by program, so confirm that your organization is a party before counting on a hearing.

A Decision Test that Fits on One Line

For each denial that has cleared the lower levels, ask four questions in order.

Does the remaining amount meet the threshold? If not, the question is whether it can be combined with similar claims under the applicable aggregation rules. If it cannot, the appeal cannot proceed to an ALJ hearing regardless of merit.

Is the record complete? Under 42 CFR § 405.1028, an ALJ or attorney adjudicator reviews new evidence submitted for the first time at the OMHA level to determine whether good cause exists for its late submission. Evidence may be excluded if the required good cause is not established. The time to build the documentation is at redetermination and reconsideration, not after. A denial with a thin record is a weaker candidate than the dollar figure suggests.

Are the dates safe? Each deadline runs from the date of receipt of the previous decision. If the receipt date is not logged, the 60-day window is guesswork.

What is the expected return against the real cost? A simple version: probability of winning times the amount in controversy, compared with staff hours plus any counsel fees. As an illustration only, a $400 denial with a 40% chance of success has an expected recovery of $160. If preparing and presenting the case takes four hours of a specialist’s time, the economics are thin, even though the claim clears the threshold. A $1,800 denial with the same odds looks quite different.

Success rates vary by claim type, and OMHA publishes decision statistics and average processing times. Use the current figures for your own claim category rather than a general impression.

Time Is Part of the Cost

Appeals guides list a 90-day decision timeframe at the ALJ level. OMHA has said for years that incoming requests exceed what its judges can decide on that schedule, and appellants may have escalation rights if a decision does not arrive in time. Check current processing times before assuming a quick answer. A dispute that is worth the money but ties up the file for many months still belongs in the cash-flow forecast.

What to Do Before January

Pull your open denials and sort them by remaining amount in controversy. Flag the ones that sit between roughly $150 and $200, where aggregation may decide the outcome, and between $1,900 and $2,000, where the 2027 change could end a court path. Then check the documentation behind the largest ones. The threshold tells you whether you may appeal. The record tells you whether you should.
